The term “dark horse” began as horse racing parlance. A dark horse is a race horse that is not known to gamblers and thus is difficult to place betting odds on. This way it has nothing to do with the horse’s color, unlike the hero of our today’s article. DFI LANPARTY DK X58-T3eH6 mainboard belongs to “LANPARTY DK” series, where “DK” stands for “dark” that is why the well-known saying came to mind. However, let’s not hurry to draw the conclusions just yet. There is some probability that the not very well-known DFI LANPARTY DK X58-T3eH6 will outperform all the LGA1366 mainboards we tested before and take the first place in this unofficial but obvious competition. Well, the review will answer all our questions and we are going to start it, as usual, with taking a look at the products and its packaging.
